Because the CO2 cost of manufacturing a new ICE car is comparable to that of a new EV, but the lifetime CO2 contribution of a new EV is far lower than that of an ICE car.
Can you prove that, because that is not my understanding. EVs use way more CO2 in their manufacturing. Not to mention the added environmental impact of battery manufacturing and lithium mining. We can't solve climate change by buying a new car.
Edit. I'm sure Musk and Tesla are super proud of the CO2 savings their company provides, so it shouldn't be hard to find the data they are publishing showing the net cost to carbon for the entire manufacturing and life time use of their product.
